Yeah, it’s was a thing in finland as well. idk what duraseal is, but I assume it’s that self-adhesive plastic wrap stuff (we called it contact plastic or something?). We could only use transparent wrap though, no fun allowed. Still, it was an important ritual I remember. New school year, 15 new books, let’s fucking go!! I was always really bad at it though, so my books would have creased wraps with tons of air bubbles. I thought it was really satisfying, so I’d (poorly) go home wrap my own books just for fun as well.
jesus christ it was right in front of us this entire time
